Subject: [patch 2/3] Input: psmouse - wrap protocol extensions (except synaptics)
 with ifdefs

Allow ALPS, LOGIPS2PP, LIFEBOOK, and TRACKPOINT protocol extensions (in
the psmouse driver) to be disabled during compilation.  The synaptics
stuff is left alone for now, since it needs special handling for
synaptic pass-through ports.
